Hi all,
I get an awful sound coming from my 190E passenger front wheel when I turn. It's like a rubbing low squeal. It originally only did it when I would turn all the way to the right. The last few days it's become much worse, everytime I move the wheel. I flushed the fluid and replaced the filter and took it about a week ago to get the tires rotated/aligned/balanced. They said they couldn't get a good alignment because the lower ball joints and idler arm needed to be replaced for around $800. But at the time, a week ago, they couldn't get it to make the sound. My question is how do I know what to replace? Idler arm bushings, control arm bushings, ball joints, which one of these, or what else, could be the culprit for this kind of noise? I understand that I may need to replace the lower ball joints and idler arm for alignment purposes but could this also the cause of the noise? Thanks in advance.

could be belts rubbing on the pulleys or rotar rubbing, not very sure though
